So I found an old desktop I had many many years ago in my parents closet. It was a very solid rig when I built it. Anyway I'm putting together a home server so I pulled the PSU from it. It's an OCZ 520adj. I think it was about $140ish back then. Was considered top of the line. Should be plenty for this machine letting me save a little. My question is if anyone has used an adjustable PSU before and why I would just turn the three settings on the back to max? I don't have a manual for it.
